User manual RANE RP 228D DATASHEET

[. . . ] DATA SHEET RPE 228d PROGRAMMABLE EQUALIZER RPE 228d Two Channel 1/3-Octave Programmable Digital Equalizer High Security Remote Control This equalizer is programmed by computer (PC compatible) via the RS-232 serial port. The computer may be removed after programming, or left connected to recall memories exclusively. A recessed Default button on the rear panel recalls Memory 1 in case of computer failure. [. . . ] The software's easy-to-use graphical interface features graphic sliders, the computed true EQ response curve, control of all parameters, and extensive on-line help. A Site Control window is provided with password protection so that all units can recall stored memories without further access. Local Edit mode allows curves to be viewed and edited without affecting a unit. The Rane RPD 1 may be used to control the RPE 228d from a remote location using a modem. The unit's firmware may be replaced with new versions, uploaded from a computer through the serial port.

There are nine terminals--one is chassis ground, and the other eight are for Memories 1-8. Momentary connection of one of these eight terminals to ground causes both channels of the unit to recall a preset Memory. Multiple units may be controlled by connecting these terminals in parallel. The translation between the eight closures and the 16 Memories is programmable. Architectural Specifications The programmable digital equalizer shall consist of two channels, each with 28 bands spaced on ISO centers from 31. 5 Hz to 16 kHz, and be 1/3-octave wide, all as specified elsewhere. The amplitude control range of each band shall be +10 dB and -10 dB, adjustable in 0. 5 dB steps. The low-cut filter range shall be 10 Hz to 200 Hz in 10 Hz steps, or OFF. The high-cut filter range shall be 1 kHz to 20 kHz in 1 kHz steps, or OFF. The overall level range for each channel shall be ±12 dB, adjustable in 1 dB steps. [. . . ] The 120 VAC model shall be powered from a UL listed, CSA certified remote power supply, and the 230 VAC model shall be powered from a remote power supply meeting LVD 73/23/EEC & EMCD 89/336/EEC standards. The unit shall be a Rane Corporation Model RPE 228d Programmable Equalizer. ©Rane Corporation 10802 47th Ave. W. , Mukilteo WA 98275-5098 TEL (425)355-6000 FAX (425)347-7757 WEB http://www. rane. com Data Sheet-4 All features & specifications subject to change without notice.
